HOBBES'S QUARRELS

WITH

DR. WALLIS THE MATHEMATICIAN.

HOBBES'S passion for the study of Mathematics began late in

life--attempts to be an original discoverer--attacked by

WALLIS--various replies and rejoinders--nearly maddened by the

opposition he encountered--after four years of truce, the war

again renewed--character of HOBBES by Dr. WALLIS, a specimen of

invective and irony; serving as a remarkable instance how the

greatest genius may come down to us disguised by the arts of an

adversary--HOBBES'S noble defence of himself; of his own great

reputation; of his politics; and of his religion--a literary

stratagem of his--reluctantly gives up the contest, which lasted

twenty years.

The Mathematical War between HOBBES and the celebrated Dr. WALLIS is

now to be opened. A series of battles, the renewed campaigns of more

than twenty years, can be described by no term less eventful. Hobbes

himself considered it as a war, and it was a war of idle ambition, in

which he took too much delight. His "Amata Mathemata" became his

pride, his pleasure, and at length his shame. He attempted to maintain

his irruption into a province he ought never to have entered in

defiance, by "a new method;" but having invaded the powerful natives,

he seems to have almost repented the folly, and retires, leaving "the

unmanageable brutes" to themselves:

Ergo meam statuo non ultra perdere opellam

Indocile expectans discere posse pecus.

His language breathes war, while he sounds his retreat, and confesses

his repulse. The Algebraists had all declared against the Invader.

Wallisius contra pugnat; victusque videbar

Algebristarum Theiologumque scholis,

Et simul eductus Castris exercitus omnis

Pugnae securus Wallisianus ovat.

And,

Pugna placet vertor--

Bella mea audisti--&c.

So that we have sufficient authority to consider this Literary Quarrel

as a war, and a "Bellum Peloponnesiacum" too, for it lasted as long.

Political, literary, and even personal feelings were called in to heat

the temperate blood of two Mathematicians.

What means this tumult in a Vestal's veins?

Hobbes was one of the many victims who lost themselves in squaring the

circle, and doubling the cube. He applied, late in life, to

mathematical studies, not so much, he says, to learn the subtile

demonstrations of its figures, as to acquire those habits of close

reasoning, so useful in the discovery of new truths, to prove or to

refute. So justly he reasoned on mathematics; but so ill he practised

the science, that it made him the most unreasonable being imaginable,

for he resisted mathematical demonstration, itself![380]

His great and original character could not but prevail in everything

he undertook; and his egotism tempted him to raise a name in the world

of Science, as he had in that of Politics and Morals. With the ardour

of a young mathematician, he exclaimed, "_Eureka!_" "I have found it."

The quadrature of the circle was indeed the common Dulcinea of the

Quixotes of the time; but they had all been disenchanted. Hobbes alone

clung to his ridiculous mistress. Repeatedly confuted, he was

perpetually resisting old reasonings and producing new ones. Were only

genius requisite for an able mathematician, Hobbes had been among the

first; but patience and docility, not fire and fancy, are necessary.

His reasonings were all paralogisms, and he had always much to say,

from not understanding the subject of his inquiries.

When Hobbes published his "De Corpore Philosophico," 1655, he there

exulted that he had solved the great mystery. Dr. Wallis, the Savilian

professor of mathematics at Oxford,[381] with a deep aversion to

Hobbes's political and religious sentiments, as he understood them,

rejoiced to see this famous combatant descending into his own arena.

He certainly was eager to meet him single-handed; for he instantly

confuted Hobbes, by his "Elenchus Geometriae Hobbianae." Hobbes, who saw

the newly-acquired province of his mathematics in danger, and which,

like every new possession, seemed to involve his honour more than was

necessary, called on all the world to be witnesses of this mighty

conflict. He now published his work in English, with a sarcastic

addition, in a magisterial tone, of "_Six Lessons to the Professors of

Mathematics in Oxford_." These were Seth Ward[382] and Wallis, both no

friends to Hobbes, and who hungered after him as a relishing morsel.

Wallis now replied in English, by "Due Correction for Mr. Hobbes, or

School-discipline for not saying his Lessons Right," 1656. That part

of controversy which is usually the last had already taken place in

their choice of phrases.[383]

In the following year the campaign was opened by Hobbes with

"~STIGMAI~; or, _marks_ of the absurd Geometry, _rural Language_,

Scottish Church-politics, and Barbarisms, of John Wallis." Quick was

the routing of these fresh forces; not one was to escape alive! for

Wallis now took the field with "Hobbiani Puncti dispunctio! or, the

undoing of Mr. Hobbes's Points; in answer to Mr. Hobbes's ~STIGMAI~,

_id est_, Stigmata Hobbii." Hobbes seems now to have been reduced to

great straits; perhaps he wondered at the obstinacy of his adversary.

It seems that Hobbes, who had been used to other studies, and who

confesses all the algebraists were against him, could not conceive a

point to exist without quantity; or a line could be drawn without

latitude; or a superficies be without depth or thickness; but

mathematicians conceive them without these qualities, when they exist

abstractedly in the mind; though, when for the purposes of science

they are produced to the senses, they necessarily have all the

qualities. It was understanding these figures, in the vulgar way,

which led Hobbes into a labyrinth of confusions and absurdities.[384]

They appear to have nearly maddened the clear and vigorous intellect

of our philosopher; for he exclaims, in one of these writings:--

"I alone am mad, or they are all out of their senses: so that no third

opinion can be taken, unless any will say that we are all mad."

Four years of truce were allowed to intervene between the next battle;

when the irrefutable Hobbes, once more collecting his weak and his

incoherent forces, arranged them, as well as he was able, into "Six

Dialogues," 1661. The utter annihilation he intended for his

antagonist fell on himself. Wallis borrowing the character of "The

Self-tormentor" from Terence, produced "Hobbius Heauton-timorumenos

(Hobbes the Self-tormentor); or, a Consideration of Mr. Hobbes's

Dialogues; addressed to Robert Boyle," 1662.

This attack of Wallis is of a very opposite character to the arid

discussion of abstract blunders in geometry. He who began with points,

and doubling the cube, and squaring the circle, now assumes a loftier

tone, and carrying his personal and moral feelings into a mere

controversy between two idle mathematicians, he has formed a solemn

invective, and edged it with irony. I hope the reader has experienced

sufficient interest in the character of Hobbes to read the long, but

curious extract I shall now transcribe, with that awe and reverence

which the old man claims. It will show how even the greatest genius

may be disguised, when viewed through the coloured medium of an

adversary. One is, however, surprised to find such a passage in a

mathematical work.

"He doth much improve; I mean he doth, _proficere in pejus_; more,

indeed, than I could reasonably have expected he would have

done;--insomuch, that I cannot but profess some relenting thoughts

(though I had formerly occasion to use him somewhat coarsely), to

see an old man thus fret and torment himself to no purpose. You,

too, should pity your antagonist; not as if he did deserve it, but

because he needs it; and as Chremes, in Terence, of his Senex, his

self-tormenting Menedemus--

Cum videam miserum hunc tam excruciarier

Miseret me ejus. Quod potero adjutabo senem.

"Consider the temper of the man, to move your pity; a person _extremely

passionate and peevish, and wholly impatient of contradiction_. A

temper which, whether it be a greater fault or torment (to one who must

so often meet with what he is so ill able to bear), is hard to say.

"And to this fretful humour you must add another as bad, which feeds

it. You are therefore next to consider him as _one highly opinionative

and magisterial_. _Fanciful_ in his conceptions, and deeply enamoured

with those _phantasmes_, without a rival. He doth not spare to

profess, upon all occasions, how incomparably he thinks himself to

have _surpassed all_, ancient, modern, schools, academies, persons,

societies, philosophers, divines, heathens, Christians; how despicable

he thinks all their writings in comparison of his; and what hopes he

hath, that, by _the sovereign command of some absolute prince, all

other doctrines being exploded, his new dictates should be_

_peremptorily imposed, to be alone taught in all schools and pulpits,

and universally submitted to_. To recount all which he speaks of

himself _magnificently_, and _contemptuously_ of others, would fill a

volume. Should some idle person read over all his books, and

collecting together his arrogant and supercilious speeches, applauding

himself, and despising all other men, set them forth in one

_synopsis_, with this title, _Hobbius de se_--what a pretty piece of

pageantry this would make!

"The admirable sweetness of your own nature has not given you the

experience of such a temper: yet your contemplation must have needs

discerned it, in those symptoms which you have seen it work in others,

like the strange effervescence, ebullition, fumes, and fetors, which

you have sometimes given yourself the content to observe, in some

active _acrimonious_ chymical _spirits_ upon the injection of some

contrariant _salts_ strangely vexing, fretting, and tormenting itself,

while it doth but administer _sport_ to the unconcerned spectator.

Which temper, being so eminent in the person we have to deal with,

your generous nature, which cannot but pity affliction, how much

soever deserved, must needs have some compassion for him: who, besides

those exquisite _torments_ wherewith he doth afflict himself, like

that

----quo Siculi non invenere Tyranni

Tormentum majus--

is unavoidably exposed to those two great _mischiefs_; an incapacity

to be _taught what he doth not know_, or to be _advised when he thinks

amiss_; and moreover, to this _inconvenience_, that he must never

_hear his faults but from his adversaries_; for those who are willing

to be reputed _friends_ must either not advertise what they see amiss,

or incommode themselves.

"But, you will ask, what need he thus torment himself? What need of

pity? If _he have hopes_ to be admitted the _sole dictator in

philosophy_, civil and natural, in schools and pulpits, and to be

owned as the only _magister sententiarum_, what would he have more?

"True, _if he have_; but what _if he have not_? That he _had_ some

hopes of such an honour, he hath not been sparing to let us know, and

was providing against the _envy_ that might attend it (_nec deprecabor

invidiam, sed augendo, ulciscar_, was his resolution); but I doubt

these hopes are at an end. He did not find (as he expected) that the

_fairies and hobgoblins_ (for such he reputes all that went before

him) did vanish presently, upon the first appearance of his

_sunshine_: and, which is worse, while he was on the one side guarding

himself against _envy_, he is, on the other side, unhappily

_surprised_ by a worse enemy, called _contempt_, and with which he is

less able to grapple.

"I forbear to mention (lest I might seem to reproach that age which I

reverence) the _disadvantages_ which he may sustain by his old age.

'Tis possible that time and age, in a person somewhat _morose_, may

have riveted faster that preconceived opinion of his own worth and

excellency beyond others. 'Tis possible, also, that he may have

_forgotten_ much of what once he knew. He may, perhaps, be sometimes

more _secure_ than _safe_; while trusting to what he thinks a firm

foundation, his footing fails him; nor always so vigilant or

quicksighted as to discern the _incoherence_ or _inconsequence_ of his

own discourses; unwilling, notwithstanding, to make use of the eyes of

other men, lest he should seem thereby to disparage his own; but

certainly (though his _will_ may be as good as ever) his _parts_ are

less vegete and nimble, as to _invention_ at least, than in his

younger days.

"While he had endeavoured only to _raise an expectation_, or put the

world in hopes of what great things he had in hand (_to render all

philosophy as clear and certain as Euclid's Elements_), if he had then

_died_, it might, perhaps, have been thought by some that the world

had been deprived of _a great philosopher_, and learning sustained an

invaluable loss, by the abortion of _so desired a piece_. But since

that _Partus Montis_ is come to light, and found to be no more than

what little animals have brought forth, and that _deformed_ enough and

_unamiable_, he might have sooner gone off the stage with more

advantage than now he is like to do; such is the misfortune for a man

to _outlive his reputation_!

"By this time, perhaps, you may see cause to _pity_ him while you see

him _falling_. But if you consider him _tumbling headlong_ from so

great a height, 'twill make some addition to that _compassion_ which

doth already begin to work. You are therefore next to consider that

when, upon the account of _geometry_, he was unsafely mounted to that

height of vanity, he did unhappily fall into the hands of two

mathematicians, who have used him so unmercifully as would have put a

person of _greater patience_ into _passion_, and meeting with such a

_temper_, have so discomposed him that he hath ever since _talked

idly_: and to augment the grief, these mathematicians were both

divines--he had rather have fallen by any other hand. These

_mathematical divines_ (a term which he had thought incomponible)

began to unravel the wrong end; and while he thought they should have

first _untiled the roof_, and by degrees gone downward, they strike at

the _foundation_, and make the building tumble all at once; and that

in such confusion, that by dashing one part against another, they make

each help to destroy the whole. They first fall upon his _last

reserve_, and rout his _mathematics_ beyond a possibility of

_rallying_; and by _firing his magazine_ upon the first assault, make

his own weapons _fight against him_. Not contented herewith, they

enter the _breach_, and pursue the _rout_ through his Logics, Physics,

Metaphysics, Theology, where they find all in confusion."

This invective and irony from this celebrated mathematician, so much

out of the path of his habitual studies, might have proved a

tremendous blow; but the genius of Hobbes was invulnerable to mere

human opposition, unless accompanied by the supernatural terrors of

penal fires or perpetual dungeons. Our hero received the whole

discharge of this battering train, and stood invulnerable, while he

returned the fire in "Considerations upon the Reputation, Loyalty,

Manners, and Religion of Thomas Hobbes, of Malmesbury, written by way

of Letter to a learned person, Dr. Wallis," 1662.

It is an extraordinary production. His lofty indignation retorts on

the feeble irony of his antagonist with keen and caustic accusations;

and the green strength of youth was still seen in the old man whose

head was covered with snows.

From this spirited apology for himself I shall give some passages.

Hobbes thus replied to Dr. Wallis, who affected to consider the old

man as a fit object for commiseration.

"You would make him contemptible, and move Mr. Boyle to pity him. This

is a way of railing too much beaten to be thought witty: besides, 'tis

no argument of your contempt to spend upon him so many angry lines, as

would have furnished you with a dozen of sermons. If you had in good

earnest despised him, you would have let him alone, as he does Dr.

Ward, Mr. Baxter, Pike, and others, that have reviled him as you do.

As for his reputation beyond the seas, it fades not yet; and because,

perhaps, you have no means to know it, I will cite you a passage of an

epistle written by a learned Frenchman to an eminent person in

France, in a volume of epistles." Hobbes quotes the passage at length,

in which his name appears joined with Galileo, Descartes, Bacon, and

Gassendi.

In reply to Wallis' sarcastic suggestion that an idle person should

collect together Hobbes's arrogant and supercilious speeches

applauding himself, under one title, _Hobbius de se_, he says--

"Let your idle person do it; Mr. Hobbes shall acknowledge them under

his hand, and be commended for it, and you scorned. A certain Roman

senator having propounded something in the assembly of the people,

which they, misliking, made a noise at, boldly bade them hold their

peace, and told them he knew better what was good for the commonwealth

than all they; and his words are transmitted to us as an argument of

his virtue; _so much do truth and vanity alter the complexion of

self-praise_. You can have very little skill in morality, that cannot

see the justice of commending a man's self, as well as of anything

else, in his own defence; and it was want of prudence in you to

constrain him to a thing that would so much displease you.

"When you make his _age_ a reproach to him, and show no cause that

might impair the faculties of his mind, but only age, I admire how you

saw not that you reproached all old men in the world as much as him,

and warranted all young men, at a certain time which they themselves

shall define, to call you _fool_! Your dislike of old age you have

also otherwise sufficiently signified, in venturing so fairly as you

have done to escape it. But that is no great matter to one that hath

so many marks upon him of much greater reproaches. By Mr. Hobbes's

calculation, that derives prudence from experience, and experience

from age, you are a very young man; but, by your own reckoning, you

are older already than Methuselah.

"During the late trouble, who made both Oliver and the people mad but

the preachers of your principles? But besides the wickedness, see the

folly of it. You thought to make them mad, but just to such a degree

as should serve your own turn; that is to say, mad, and yet just as

wise as yourselves. Were you not very imprudent to think to govern

madness?"--p. 15.

"The king was hunted as a partridge in the mountains, and though the

hounds have been hanged, yet the hunters were as guilty as they, and

deserved no less punishment. And the decypherers (Wallis had

decyphered the royal letters),[385] and all that blew the horn, are to

be reckoned among the hunters. Perhaps you would not have had the prey

killed, but rather have kept it tame. And yet who can tell? I have

read of few kings deprived of their power by their own subjects that

have lived any long time after it, for reasons that every man is able

to conjecture."
